Organelle present in animal cells that specialize in the digestion of macromolecules.
Lysosomes
The structure and function of the flagella
Structure: cluster of microtubules Function: mobility
True or False? Only animal cells have mitochondria.
False
The function of tight junctions in animal cells
Tight junctions prevent leakage of extracellular fluid
________ fasten neighboring animal cells together
Desmosomes
True or false? Plant cells have a more rigid structure than Animal cells. Due to what cell structure?
True. Because of the cell wall
Function of the central vacuole
1.Holds reserves for organic compounds 2. cell’s storage of inorganic ions 3. Disposal sites for metabolic by-products
This plant cell organelle is the site of photosynthesis
Chloroplasts
Components of the cell wall
cellulose, other polysaccharides, and protein
These channels connect the cytoplasm of adjacent cells (located in the cell wall)
Plasmodesmata
What is the theory explaining the vast diversity of protists?
Endosymbiosis
The internal membrane system of eukaryotic cells may have originated from this occurrence in ancestral prokaryotic cells.
The infolding of the plasma membrane
Microorganisms that live within a host cell and perform specified functions are called
Endosymbionts
What is the origin of chloroplasts?
Photosynthetic bacteria
Evidence of endosymbiosis (Answers may vary)
1. mitochondria and chloroplasts both have their OWN DNA, similar to that of bacteria 2. Both mitochondria and chloroplasts have TWO membranes
True or False? Both Eukaryotes and Prokaryotes have a membrane bound nucleus
False, only eukaryotes have a membrane bound nucleus
Prokaryotes “reproduce” (asexual) through this process
Binary Fission
A region in the prokaryotic cell where the DNA is located (not bound by a membrane)
nucleoid
True or False? A prokaryotic cell and a eukaryotic cell contain ribosomes.
True
Three structure found in both eukaryotes and prokaryotes (Answers may vary)
1.Ribosomes 2. Plasma membrane 3. Cytoplasm
